Applicatiog filed November 8, 1915. Serial No. 60,220.

Y To all whom it may concern Be it known that 1, WILLIAM H. Lecture, a citizen of the United States, residing at Hartford, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Badlators, of which the following is a specification.

This invention relates to radiators. A radiator involving my invention is comparatively light, yet possesses unusual strength.

It is simple in construction, consisting practically of merely three parts. lit can be easily taken apart for repairsior other pur poses, Water or its equivalent can freely circulate longitudinally and laterally of the body and can uniformly reach all the parts thereof, said body being of such construction as to permit thorough circulation of a1r therethrough to aid in maintammg the water cool or to perform someother equivalent office. In addition to this the radiating surface is of considerable extent.

The device possesses other featuresof ad vantage and novelty which with the foregoing will be stated at length m the following description wherein I Wlll set forth 1n detail that form of embodiment of the 1nvention which I have selected for illustra-' tion in the, drawings accompanying and forming part of the present specification. I do not limit myself to this particular d1sclosure; I may depart therefrom in several res ects within the scope of the invent on de ned by the claims following said description.

Referring to said drawings:

Fi re 1 is a perspective view of a radiator involving my invention as viewed from the inside or back' thereof.

Fig. 2 is a front elevation of one side of said radiator.

Fig. 3 is a vertical sectional view of'the same.

Fig. 4 is a perspective view of a mold.

Fig. 5 is a detail with parts broken away of a portion of a core.

member showing a way of removing the core therefrom.

Fig. 7 is a sectional elevation of a part of the body of the radiator with the incased core.

Fig. 8 is a sectional view of a portion of the body of the radiator, and,

Fig. 9 is a similar view showing more of degrees Fahrenheit.

the body, the interior skin or coating not being shown in Fig. 9, but appearing in Fig. 8 for the reason that the latter is ona larger scale than the former.

Like characters refer 'to like parts throughout the several views, which it will be noted are on different scales.

The present case is a division of my application for patent for method of making radiators, filed May 27, 1915, berial No.

mobile, providing as will be understood,

ihe dr'awingsconstituting a partthe necessary water to keep the engine in a relatively-cool condition. The radiator includes a body of grid-like tubular construction and a crown or head pan and a settlingor base pan suitably associated together as will hereinafter appear. The Woody? as I havetermed it, may be and preferably is made through the intervention of a core of some suitable material such as a lead composition which can be easily fused, for. instance at a temperature of 202 This body has deposited upon it for instance, electrolytically, a metal which may be either copper or brass, the former being quite advantageous. After the metal is deposited on the core, the core is removed, for instance by heat, leaving the grid-like tubular body, and when a lead composition is provided the lead will coat v the interior of thetubular like. body" with a protective skin. With the foregoing general observations'I will now describe more in detail what is illustrated in the annexed drawings.

Initially or at some primary stage in the manufacture of the radiator I utilize a gridlike member which is .of such character as to be subsequently removed from an integral or one-piece body formed on it. If the external body he of copper, for instance, the interior member would preferably be mating to produce passages fully circular in.

fusible. For example the grid-like core can advantageously consist of some lead composition which will fuse as already noted at about 202 degrees Fahrenheit. In Fig. 4 I

have shown amold 2 which is made of some .suitable material,- bronze answering satisfactorily in this respect. The sections of themold have longitudinally extending channels 3 and transversely extending" channels 4 intersecting the longitudinally extending channels, the channels in the mold sections cross section. From the outside channels in the body section of the mold the bores 5 depend, these bores 5 being fully circular in cross section. The mold has the gate 6 into which the metal to form a grid .is poured. When the sections of the mold are closed together molten metal is poured into the mold by way of the gate 6, and it fills the space so as to produce a grid such as that denoted in a general way by 7. The

mold and the grid therein havebeen .shown of comparatively small size, this for economy in space and simplicity of illustration. It is a matter of fact, however, that there may be any number of longitudinally extending and any number of transversely ex tending bars in a grid as 7. In Fig. 4 the upper section of the mold is swung up so that the grid 7 can be removed therefromif cool. Before forming the body of the radiator, the fin 8 left by casting is removed from the grid 7. It will be clear that said grid comprises a number of longitudinally extending and-a number of transversely extending bars or rods, and although these I are circular in cross section, it is not necessary that they be made in such shape, butsuch form is advantageous, in that no angles are presented in the body of the radiator in the length of the tubes thereof. In addition I to the longitudinally extending and transversely extending rods or bars of the grid 5 so as to produce a duplex grid. As a matter of fact there may be any number f these fusible grids connected together. I he connected grids are then coated with the necessary metal which is to form the tubular body of the radiator, and copper or brass answer satisfactorily in this respect, copper in fact' being preferable. After the two grids 7 have been united, or after the sections of the fusible core have been connected together as it might otherwise be put, the

core is in readiness to be coated, for exam le by being'immersed in a hot copper.

sul ate solution, copper being electrolytically deposited upon the core to the requisite thickness, for illustration somewherebetween twenty to forty thousandths of an inch thick. After the core is plated, it is taken from the bath and cleaned, subsequent to which it is put in an oven and subjected .to heat of approximately 202 degrees Fahrenheit, which melts the core, the core in molten condition running from the tubular body as shown in Fig. 6 which might be assumed to represent One of the longitudinally extending tubes 10 of the radiator body denoted in a general way by 11. There will be two'series of such longitudinally or,

vertically extending tubes 10, one at the front andthe other at theback of said body, the side tubes of the two series being united by connecting tubes 12. The longitudinally or vertically extending tubes 10 are connected by transverse tubes 13. As wilLbe inlar grid and a rear tubular grid in communication with each other by way of 0011- necting tubes, all the tubes in fact being in communication with each other to provide for'the proper circulation of the cooling liquid which when the radiator is used on an automobile would be water under ordinary circumstances. While the longitudinally and transversely extending and connecting tubes of the body 11 are disposed at right angles to each other, this may not always be necessary. It will be clear that all the tubes when a fusible core is utilized in the formation of said body are interiorly coated with the fusible material, sufiicient of the material remaining for this purpose. Fig. 9 represents a portion of the body 11. The tubes are not shown coated, the coating being omitted on account of the smallness of scale of this particular view. Fig.8 is on a larger scale and shows the coating in the tubes of the body. The 'interiorly coated shell-like or hollow body is now in readiness for assemblage with the remaining parts of the radiator. In addition to the body 11, said radiator comprises a base or settling tank or pan 1 4 and a crown tank or pan 15. The upper or head tank is provided with a discharge nipple or tube 16 adapted to be connected in some suitable way with the water spaceof the engine, this water space delivering in turn (through suitable connections with the nipple or tube 17), the water or other liquid after it has exercised its function. This nipple or tube 17 is connected with the base or settling tank 14. The upper tank 15 is provided with the removable screw-threaded cap 18 such as is .cast integral, their inner walls being per forated near the front and rear thereof to receive the upper and lower terminals of the longitudinally extending rods 10 of the reticulated 0r foraminous hollow or tubular body'll, said terminals being soldered or welded or otherwise secured in a liquidtigh manner in the respective perforations. Preferably formed integrally with the lower pan 14 are the side members 20 of practically duplicate construction and which re sent in fact the sides of the radiator. Ehe

ends of the upper pan or tank 15 are rabbeted or channeled as at 21 to receive "the upper ends of the side members 20, said side members being fastened to the upper pan in any desirable manner as by screws 22 tapped into the end portions of said upper pan 15. The heads of the screws are countersunk in said side members 20 and after the screws have been driven home solder 23 will be flowed into the slots of the screws. The side members 20 have as shown inwardly extending flanges, the upper ends of which abut against the bottom of-the pan 15 to aidin upholding the pan, the flanges overlying the front of the radiator body ll at the sides thereof. The upper ends of the side members 20 it will be noticed,

abut against the tops of the rabbets 21 to further aid in upholding the pan 15. It

will be clear, therefore, that the flanges 24 e are not coextensive with the side members 20 but extend short of the upper ends thereof.

It should be noted that the ends of the transversely extending tubes of the gridlike body of the radiator abut against the sides 20 and that these sides actually close in a lict uid tight manner, the opposite open ends 0 the transversely extending tubes of said grid-like body.

WhatI claim is: v

1.. A radiator comprising an integral body having longitudinally and transversely disposed connected and communicating tubes,

tanks in which the longitudinally extending tubes are fitted in a liquid tight manner, and side pieces between the tanks, the ends of the transverse tubes-being open and said side pieces closing the outer ends of the transversely extending tubes.

2. A radiator comprising an integral body having longitudinally and transversely disposed tubes in two series and also having tubes extending from front to rear and connecting the two series of tubes, and tanks having openings in which the two series of longitudinally extending tubes are fitted in a hquid-tight mann r, the ends of the transversely disposed tu es being open, and side pieces connecting the two tanks and closing the openends of the transversely disposed tubes.
